Any way to convert flipkart/snapdeal/woohoo into cash or a prepaid card

Hi
Hdfc diners card is giving 10 times the point on purchases at snapdeal or flipkart. And from snapdeal one can buy woohoo gift card. I want to collect maximum points as soon as possible so what can be the way to convert my purchases into cash or a prepaid visa card at minimum loss?
Please give your suggestions

One way I could think of is by buying products priced low on these websites and sell it on eBay but that requires a bit too much of effort and hassle of handling complaints of buyer.

Buying gold could be another option but I am not sure if they give points on purchases of gold coins.
